Veken
A plug-in 3.2 L fountain with a 304 stainless steel tray and top-access filter; the listing says its seven parts snap apart without tools.
One or two cats in a home where a weekly dishwasher or sink wash is realistic and a wall outlet is nearby.
Anyone who wants app tracking, cordless placement or a camera. Reviews on the listing are mixed on pump durability, so keep the proof of purchase.
The current Amazon listing identifies this as the C2 108 oz model and lists a top-access filter, seven tool-free parts, and a weekly cleaning schedule. The maker also gives a four-week filter and pre-filter sponge interval. These are product-page and maker instructions, not our test results; confirm replacement filters and care directions for the exact model before ordering.

Slime builds up in every recirculating fountain. Here is a five-step weekly routine, the filter schedules the makers publish, and a six-slide carousel you can post.

A 45-second comparison video that answers the one question cat owners ask after the purchase: how much work is it to keep clean? Shot list, caption and facts included.
